摘　　要：旱灾是我国主要的自然灾害之一。近年,我国干旱灾害发生频繁,对经济社会造成的影响不断加剧。加强旱情监测,提高旱情综合评判能力,探索旱情预警方法等,显得十分必要和紧迫。目前,我国旱情监测工作相对薄弱,旱情预测预报起步较晚,旱情预警尚处于研究和探索阶段。结合吉林省旱情预警模型研究的有关成果,探讨预警指标、预测模型、预警综合指数等主要技术问题的创建思路,为旱情预警系统研究提供借鉴和参考。Drought is one of the main nature disasters in China. In recent years, drought has been frequently happened that results in serious impact on economy and society. It becomes increasingly important and urgent of strengthening drought monitoring, ability of drought condition assessment and early warning. However, the ability of conducting drought monitoring and early warning is rather weak in China. Therefore, the result of model for drought monitoring and early warning in Jilin Province is used for examining technical problems associated with creation of early warning indicators, model and comprehensive indexes, so as to provide reference for studies of drought early-warning system.
